The efficacy of the EMDR treatment will be evaluated by comparing the results of the tools (CAPS, CMDI, HADS, FAMS) administered to the treated group at T0, T1 and T2 and by comparing the scores of the experimental group with those of the control group. Primary outcome measures will include 1) Proportion of participants at T1 and T2 no longer meeting the DSM IV-TR diagnostic criteria for PTSD (SCID) among patients of the experimental group in comparison with those of the control group; 2) the reduction of CAPS scores for the four PTSD dimensions from pre-treatment to follow-up in both groups (avoidance, re-experiencing the traumatic event, hyperarousal and numbing).
